Patent EP-0225637-A2 (EP)
Inventor: ISHIDA SHIRO FUJISAWA FACTORY
IPC: F02B3/02
Filed: 1986-12-09
Abstract: Described herein is a combustion chamber (3, 103) for internal combustion engines, including a protuberance (12,112) projecting radially inward from a peripheral wall surface (3a, 103a) of a combustion chamber (3, 103) which is formed by hollowing the top of a piston (1) in the axial direction thereof. The protuberance (12, 112) induces rolling streams turning in the same direction as the swirl, thereby collecting air and atomized fuel in a region on the upstream side of the protuberance (12, 112). 
     The rolling stream serves to improve the ignition quality by enriching the concentration of fuel vapors in that locality. The flames generated in the vicinity of the protuberance (12,112) are propagated to the atomized fuel which is supplied to other regions of the combustion chamber (3, 103), permitting to provide an internal combustion engine with improved ignition and combustion qualities.

Abstract: A deglitching network for digital logic circuits includes a voltage actuated current source coupled to a linear tracking, constant voltage column clamp circuit. The deglitching network threshold level tracks closely with the predetermined voltage of the column clamp, which also acts as a current sink. When heavy current loads are switched from the column clamp and its voltage falls briefly, the deglitching network is actuated to inject current into the column clamp circuit and restore the preset voltage.

Abstract: A self-inking, automatic rubber stamping device (10), comprising a rubber stamp support plate (22) moveable between a face-down, stamping position and a retracted position where it faces an ink pad (18). The ink pad is mounted in a vertical position, and the movement of the plate is governed by a combination of guide-slots (34, 36, 38, 40) so that during non-use of the device, the rubber stamp is not pressed against the ink pad, but kept apart therefrom. During every stamping cycle, the plate first approaches the pad to become wetted with ink, and then retracts and becomes overturned into the face-down stamping position.

Abstract: An optic fiber connection system is provided which enables the forming of a lens or bead (112) at the end of an optic fiber (114) and the positioning of the lens for coupling to another optic fiber. The contact (118) has a front end portion formed of a dielectric. A hole extends along the contact axis for receiving the optic fiber. A cross aperture in the dielectric front end portion extends perpendicular to the hole. With the tip of the optic fiber lying in the cross aperture, heat is applied to the tip to form a nearly spherically shaped lens thereon by electric arc heating. Because the front end portion is formed of a dielectric, it does not interfere with the creation of the arc and the heating of the fiber. The arc (132) is formed by positioning the tips (120,122) of a pair of electrodes (124,126) to lie slightly within opposite ends of the cross-aperture, to avoid establishing an arc between the electrodes which passes around the contact instead of through the cross-aperture. The electrodes are spaced apart by at least about eight times the diameter of the optic fiber, to avoid deposition of vapors from the heated optic fiber onto the electrodes.

Abstract: A control system is described for a continuously variable transmission having a spool type transmission ratio control valve for controlling oil supply to a cylinder of a drive pulley of the transmission in order to change the transmission ratio. The transmission ratio control valve is itself controlled by a hydraulic circuit (Figure 2b of the system). By controlling flow of oil supplied to the spool valve in accordance with a desired transmission ratio, the spool is shifted, so that the transmission ratio changing speed is controlled. In the invention the transmission ratio changing speed is corrected in response to the speed of changing of the desired transmission ratio.

Abstract: Semiconductor dopant sources are prepared by mixing particles of elemental silicon and at least one dopant oxide and heating the mixture to a temperature sufficient to initiate a reduction reaction while excluding external oxygen sources from affecting the reaction. The reaction can be initiated in a furnace, provided the gaseous ambient is controlled, or can be initiated in air if the mixture is heated sufficiently rapidly, e.g. by heating with electromagnetic energy at microwave frequencies. The dopant source produced includes a fused, amorphous matrix of silicon-oxygen-dopant atoms containing inclusions of elemental dopant and, preferably, inclusions of elemental silicon. Embodiments of sources prepared from antimony trioxide slowly evolve antimony, have a long life and repeatedly and predictably dope silicon at commercially useful levels.

Abstract: The circuit involves a charge-transfer matrix device. The detecting system (12, 13, 14) immediately triggers an exposure when the object (3) arrives in its inspection position and also triggers the emission of image signals by the matrix device. A system for analysis (15, 16, 17, RP) processes in sequence the electrical level of the successive signals emitted by each elementary matrix point, taking into account the elementary points in the immediate neighbourhood. A circuit (18, 19) compares the level corresponding to each elementary point which has been weighted in this way with a predetermined adjustable reference level. A circuit (20) counts the number of elementary points considered in this way as being outside the required standard and emits a signal of rejection for each object thus considered as lying outside the standard. <IMAGE>
